There are quite a lot of questions about chess, some of them are classified as combinatorial-game-theory, which is (sometimes) incorrect.
Chess it not a mathematical field; however, I can easily imagine people (like myself) that are interested in mathematical questions having chess as a "background" or as a "story" on which the question is being built.
A similar tag - card-games - already exists.
Do you agree, such a tag should be added?
